Hi, When I use either LiveUpdate or the Updater file 20111121-003-x86.exe, the update completes OK, but when I reboot the PC the AutoProtect is turned off. When I try to turn AutoProtect on I get the error message 'Norton AntiVirus has encountered an internal program error'. I am using NIS 2005 on Windows XP pro SP3. I know this is an old Norton product, however the Norton Update page still shows 2005 as a compatible program for the 20111121-003-x86.exe file and should therefore work without error. Any help would be much appreciated.
